Piling Services

Piling is a deep foundation technique that transfers loads from structures to deeper, more stable soil layers. Different types of piling methods are based on installation techniques and materials used. Here are the main types:

1. Driven Piles (Displacement Piles)

Driven piles, or displacement piles, are deep foundation elements installed by driving them into the ground using impact hammers or vibration. As driven piles penetrate the soil, they displace it laterally, increasing soil density and providing strong load-bearing capacity. Driven piles are commonly made of concrete, steel, or timber and are ideal for structures requiring high stability, such as bridges and high-rise buildings. Installing driven piles is quick and efficient, making them a preferred choice for many construction projects.

Different ways of casting Driven Piles (Displacement Piles)

• Precast Concrete Piles – Factory-made and driven into place.
• Steel H-Piles – Steel sections driven into the ground, often used for deep foundations.
• Timber Piles – Used for lightweight structures, typically in marine environments.
• Steel Pipe Piles – Hollow steel tubes driven into the ground, sometimes filled with concrete.

2. Bored Piles (Non-Displacement Piles)

Bored Piles (Non-Displacement Piles) are deep foundation elements created by drilling a hole into the ground and filling it with concrete and reinforcement. Unlike driven piles, Bored Piles (Non-Displacement Piles) do not displace the surrounding soil, making them suitable for sites with sensitive structures nearby. Bored Piles (Non-Displacement Piles) are commonly used for bridges, high-rise buildings, and heavy load-bearing structures due to their high load capacity and adaptability to various soil conditions.

Different Ways of casting Bored Piles (Non-Displacement Piles)

• Drilled Shafts (Caissons) – Large-diameter bored piles often used for bridges.
• Continuous Flight Auger (CFA) Piles – Drilled and concreted simultaneously to prevent collapse.
• Underreamed Piles – Feature a widened base for extra load-bearing capacity.

3. Screw Piles (Helical Piles)

Screw Piles (Helical Piles) are deep foundation elements with helical blades that are screwed into the ground, providing strong support with minimal soil disturbance. Screw Piles (Helical Piles) are ideal for projects requiring quick installation, such as lightweight structures, boardwalks, and solar panel foundations. The design of Screw Piles (Helical Piles) allows them to bear loads through both end-bearing and friction, making them a versatile choice for various soil conditions.

4. Micro Piles (Mini Piles)

Micro Piles (Mini Piles) are small-diameter deep foundation elements that strengthen existing structures and support new construction in restricted spaces. Micro Piles (Mini Piles) are installed by drilling and injecting grout, making them ideal for sites with difficult soil conditions or limited access. Due to their versatility and high load-bearing capacity, Micro Piles (Mini Piles) are commonly used in foundation repairs, bridge supports, and seismic retrofitting.

5. Sheet Piles

Sheet Piles are thin, interlocking steel, vinyl, or timber sections used to create retaining walls and prevent soil or water movement. Due to their strength and durability, Sheet Piles are commonly used in marine structures, cofferdams, and excavation support. The installation of Sheet Piles involves driving them into the ground to form a continuous barrier, providing stability and protection in various construction projects.
